6yo DD came home from school on Monday night and had diarrhoea. It was quite bad to the point she had an accident in her pants, we kept her off of school and she had an accident again on Wednesday in the early hours, but nothing after and it seemed like it was better. She has come home from school today and has had yet another accident in her pants, she said she hadn't realised she had done a poo. She has no other symptoms, is running about playing and is otherwise eating and drinking fine. I have no idea what it could be, is this something to take her to the Dr about? Do I send her in tomorrow?
